feat: Increase secret size to 256 bits of entropy

Browse Source 
This is for quantumn computers. When trying to break AES, quantumn
computers give a square-root speedup, i.e. the 144 bits of entropy would
take as many queries as breaking 72 bits of entropy on a normal computer. This neglects
e.g. the costs of quantumn circuits and quantumn error correction [1], so,
144 bits entropy would actually have been fine, but in order to be on
the very safe side and so that noone can complain, let's increase it to
256 bits.
